Method of fabricating solid oxide fuel cell electrodes

A method of making an anode electrode for a solid oxide fuel cell, comprising the steps of:

• forming an element comprising a first electrically conductive pattern of an electrolyte tape and electrically conducting tape;
• said electrically conductive tape includes said electrolyte component from 0 vol. % to not more than 5 vol. % and a conductive component;
• creating a plurality of subelements from said element, each subelement having a structured network of defined areas of said electrolyte component physically separated from defined areas of conductive component that provides said first electrically conductive pattern;
• and
• juxtaposing said subelements to form said anode electrode, the step of juxtaposing comprising the step of orienting in a non-parallel angle said subelements to one another in parallel planes and placing in electrical contact said first electrically conductive patterns of adjacent subelements such that a second electrically conductive pattern of electrolyte tape and electrically conducting tape that is different from said first electrically conductive pattern is formed in said electrode.

A method of making an anode electrode for a solid oxide fuel cell, comprising the steps of:

• forming an element comprising a plurality of layers of an electrically conductive tape of anode material devoid of an electrolyte component and an electrolyte tape, said plurality of layers forming a first electrically conductive pattern;
• creating a plurality of subelements from said element, each subelement having a structured network of defined active areas of said electrolyte component physically separated from defined active areas of a conductive component in said electrically conductive tape that provides said first electrically conductive pattern;
• juxtaposing a plurality of said subelements;
• and
• rotating in planes substantially parallel to one another a plurality of said subelements such that a totality of said first electrically conductive patterns form a second electrically conductive pattern of said electrically conductive tape in said anode wherein said first and second electrically conductive patterns are different from one another.
